Just bought a new bike (early Christmas present!) and it came with Conti Gransport 'race' x23

My bike (and my sons) have ran Bonty hardcase tires with pretty good results. (his 700x25, 2 flats in 3 years - mine 26x1.5 slicks on mtb, 2-3 rides per week 4-5 hours a week weather permitting)

I basically drive fairly nice roads to blacktop trail system, I dont do any crazy cornering, althought I do like to try to go fast in a straight line - I have never carried tubes or inflator yet

I am debating on
1) put Mr Tuffy liners in my stock Conti gransorts

2) Run stock tires as is

Or sell stock tires as take offs
- and get something like Bonty hardcase again or Conti Gatorskins, etc

Thanks in advance

Ride what you have but watch the PSI in each tire like your life depends on it!! Low tire PSI is a death wish for any tire.

Don't obsess about flats. My experience has been that no matter what I do, sometimes I have more than at other times. This past year, for example, I had a single puncture during the whole road riding season. I always carry a couple of spare inner tubes, along with a pump and tools needed for flat repair. As noted before, I only needed them for myself once, although my pump was used several times by others on group rides. Your stock tires are fine. Even puncture resistant tires are vulnerable to pinch flats no matter what you do. . One thing that I do not do is to ride until my tires are paper thin. At that point almost anything can puncture your tires. The best possible way to protect yourself is to be able to effect a repair on the road, by having the needed supplies and ability to quickly get going again. You will have lifted a cloud from above your head and you will be able to ride without worrying about your tires

You can upgrade to tires with built in puncture protection. Its well worth the added weight and I've never had a flat yet.

Beats having to do a repair on the side of the road or having to walk home with my bike.

I've had good luck with the Fyxation Session 700. One flat in two and a half years of Chicago commuting (knock on wood). I have the 35mm, but they make them in 23mm if you want. They have an urban look to them, so if you'd prefer something sportier look at Schwalbe - their name comes up a lot in tire threads here.

In general, high performance tires are very supple, light and thin. They perform better an all ways (ride quality, rolling resistance, road holding) except for tread wear and puncture resistance. Improving tread wear and puncture resistance generally makes tires heavier and stiffer so they handle less well.

Bicycle tire manufacturers produce a variety of models with a range of performance and puncture resistant characteristics. Finding the right model for the way that you ride is a kind of hunt and peck process. Since it sounds to me like you have found a model that you like, I don't know why you would want to change.

Good luck.
